Member Function Documentation

const MesgProps& Sawyer::Message::Destination::defaultPropertiesNS ( ) const

inline

Default values for message properties.

Any message property that has no value coming from a higher layer in the plumbing lattice will be set to the default value if one is defined.

Thread safety: Not thread safe.

Definition at line 627 of file Message.h.

MesgProps& Sawyer::Message::Destination::defaultPropertiesNS ( )

inline

Default values for message properties.

Any message property that has no value coming from a higher layer in the plumbing lattice will be set to the default value if one is defined.

Thread safety: Not thread safe.

Definition at line 628 of file Message.h.

const MesgProps& Sawyer::Message::Destination::overridePropertiesNS ( ) const

inline

Overrides message properties.

Any overriding property value that is defined will override the value coming from a higher layer in the plumbing lattice.

Thread safety: Not thread safe.

Definition at line 639 of file Message.h.

MesgProps& Sawyer::Message::Destination::overridePropertiesNS ( )

inline

Overrides message properties.

Any overriding property value that is defined will override the value coming from a higher layer in the plumbing lattice.

Thread safety: Not thread safe.

Definition at line 640 of file Message.h.

virtual void Sawyer::Message::Destination::bakeDestinations ( const MesgProps &  , BakedDestinations &  baked  )

virtual

Bakes message properties according to the plumbing lattice.

The given message properties are applied to the plumbing lattice rooted at this Destination, adjusted according to the default and override properties at this node of the lattice and all lower nodes. The property values at the bottom nodes of the lattice are appended to the baked argument.

Thread safety: All implementations must be thread-safe.

Reimplemented in Sawyer::Message::Filter, and Sawyer::Message::Multiplexer.

virtual void Sawyer::Message::Destination::post ( const Mesg &  , const MesgProps &  bakedProperties  )

pure virtual

Causes a message to be emitted.

The bakedProperties argument is one of the values returned by the bakeDestinations method.

Implemented in Sawyer::Message::SyslogSink, Sawyer::Message::StreamSink, Sawyer::Message::FileSink, Sawyer::Message::FdSink, and Sawyer::Message::Multiplexer.

MesgProps Sawyer::Message::Destination::mergePropertiesNS

(

const MesgProps &

props

)

Merge properties of this lattice node into the specified properties.

Any property in props that is not set will be set to this node's default value for the property (if any). Any override property defined for this node will override the value (or lack of value) in props. The merged result is returned.

Thread safety: Not thread safe.
